Necklaces composed of separate cylindrical elements having theirperipheral surfaces set with stones have hitherto been made from solidmetal discs, in which the apertures for the reception of the stones havebeen produced by boring or else by turning suitable rings. The stoneswere then secured in the first case by cementing them in and in thesecond case by flanging over the margins of the disc. 7

The necklace elements or beads thus produced were heavy. In consequenceof the great waste of material and the tedious and complicated work theywere also expensive,

and the stones were not very securely set.

Necklace elements made according to the present invention are on thecontrary light,

and therefore cheaper, and make ordinary stone setting quite reliable.The manufacture is exceedingly simple.

The invention consists in producing two thin suitably embossed orstamped metal discs, with or without flanged edges, which, whenassembled, form round grooves for the stones to be inserted orelse'recesses shaped to fit the stones, and which, after the insertionof the stones, are riveted or soldered together or connected by means ofa link, key, cotter or the like.

The invention is illustrated by way of example in the accompanyingdrawings, in which,-

V Figure 5 is a sectional view of a constructional form in whichseparate cover plates are employed, and

' Figure 6 shows in section the combination of a plurality of necklaceelements by means of a link or pin to form a chain unit. 7

Each necklace element comprises at least two thin embossed metal plates1 and 2, with may differ in form and may be of. various or withoutflanged edges. The two plates.

profiles according to the effect contemplated.

Each two metal plates fit on to one another. They have in the centre thenecessary holes 3 and 4 for threading them on a string or for link pinsfor joining them together. .Furthermore the metal plates 1 and 2 maycomprise indentations adapted to fit into one another, which serve toprevent relative rotation of the discs 1 and 2. The margins 6 and 7 areformed with embossed cavities or grooves corresponding to the stones tobe inserted. One of the two metal plates receives in all cases the formof the stones 10, embossed at a suitable distance apart round themargin. The second metal disc may also receive the same form in acorresponding position. Usually it is sufiicient to form in the secondmetal plate a hollow embossed groove 6. The flanging of the edges of thetwo metal plates 1 and 2 may if preferred be omitted. In this case theedges which. serve for the setting of the stones are replaced by simplecover plates 11 and 12 with flanged edges, as shown in Fig. 5. Betweenthe margins thus embossed, or the setting produced in either I of theaforementioned ways, the stones 10 are then secured. I

The insertion of the stones is eflected in the following manner Onemetal plate embossed to correspond to the shapes of the stones is laiddown and the stones are deposited in the recesses thereof.

The second and corresponding disc is then placed thereon in such a waythat the indentations 5 in the two plates register with one another. Theclosing is then efiected' by means of an eye 8 and a pair of springtweezers. The eye 8 is passed through the holes 3 and 4. It may ifpreferred form part of one of the two metal plates, preferably the lowerone, provided with the shaped hollows of the stones, as shown in Fig. 4.The joining of the metal plates may be efiected by soldering, for whichpurpose the plates 1 and 2 are provided with holes 9 besides thecorresponding indentations 5. It is also possible to connect the platesby means of a link pin 13, as shown in Figure 6. In the case ofbutton-like perforations of the disc, the necklace elements may also beemployed for hand work. It

may be just mentioned in connection there with that in consequence ofthe employment of embossed metal plates the nature of the setting admitsof being varied according to taste without making the article moreexpensive, which was hitherto not possible. Furthermore it is possibleto combine in various ways'elements of different sizes and thereby usethe element in a great variety of ways. lVhat I claim is 1. A necklaceelement, comprising two embossed metal plates secured together, the formof the plates being such that when they are secured together theyjointly form a series of peripheral cavities each adapted to receive onestone.

2. A necklace element, comprising two embossed metal plates each formedwith a hole in the centre, and a hollow cylindrical eye adapted toextend from the central hole in one plate through the central hole inthe other plate tojoin the plates together, the form of the plates beingsuch that when they are secured together they jointly form a series ofperipheral cavities each adapted to receive one stone.

3. A necklace element, comprising two embossed metal plates solderedtogether, the form of the plates being such that when they are securedtogether they jointly form a series of peripheral cavities each adaptedto receive one stone.

4. A necklace element, comprising two embossed metal plates securedtogether, of which one has around its circumference a series ofdepressions, the other having an embossed groove for the purpose offorming a series of peripheral cavities each adapted to receive onestone.

5. A multiple necklace element, comprising an even number of metalplates secured together in pairs, each formed with a hole in the center,the form of the plates being such that when they are secured togetherthey jointly form a series of preipheral cavities each adapted toreceive one stone, a link pin passing through the centers of all themetal plates to join the several pairs of plates into a unit, and ringsformed at the end of the link pin to enable the multiple elements to belinked together to form a chain.

In testimony whereof I have signed my name to this specification.
